External Drives Slowing down everything

Hi,

I bought 2 USB 2.0 exernal drives, 500gb each, to make a RAID 1 array. I already have a 250gb internal and a 250gb external FW drive and have have no problems to this point. As soon I plugged them in and formatted them, everything slowed way down - especially file operations in Finder. Basically, if I click on a file to get info or empty trash etc, the globe spins and spins and spins and spins, and then finally does what I asked it to do. Like minutes later. I ejected the drives, and voila everything speeds up again.





What gives? I don't have a problem with just using them for backups and turning them off when I'm not doing backups, but the speed thing makes backing up a total pain in the ass?



Also, I've been been meaning to ask this - should I crack my 250fw drive open and install it internally?
